Hi
I accessed my webcam using OpenCV, and I am getting Mat of the RAW image, I want to pass this into ffmpeg to encode the stream, how do I go about doing this?

Thanks in advance.

More explanation is required. What encoding? Why not use ffmpeg directly without opencv.

Having read your other question on a related matter I will answer here. You need to convert a cv image (cv::Mat) to an AVFrame.

This should get you well and truly started:

This may also be of interest (I include it because I am not clear on what your requirement is):
